To all whom t may concern:

Be it known that l., GEORGE H. GIDDIN-os, a citizen of the United Sta-tes, residing at Ilion, in the county of Herkimer and State of New York have invented a new and use-V ful Improvement in Brooch-Loading Firearms, of which the following is a specification.

My invention relates generally to breech loading fire arms and has for its object toV provide a. simple, effective and reasonably cheap loch mechanism for such guns.

My improvements relate particularly to the cooking mechanism in connection with a novel construction of safety mechanism., and the construction and arrangement of these parts are such as to permit the arrange ment of a novel construction of barrel loching mechanism, all of these various combinations being arranged 1n that type of arm in which removable lock plates are secured barrel broken down and the hammers nearly cocked. Fig. 3 is a similar view showing the hammers at full cook and the safety indicator at the pointindicating safety. Fig. 4. is a transverse sectional. view taire-n on the line 4 4 of Fig. 2, and Fig. dis a similar view taken on the line 5-5 of Fig. 1. Fig. is a view showing side and end views of a bolt or check 'used in connection with the barrel locking bolt. Figs. 7 and 8 are views illustrating the manner of disconnecting the barrel from the frame and also illustrating the means for operating the cooking lever. Fig. 9 is al view showing side and edge views of one of the lock plates with the parts connected thereto. Fig. 10 is a viewshowing the side and end views of a cooking lever, and Fig. 11 is a bottom plan view of the barrel locking 1ooltand the rod attached thereto for carrying the spring.

ln the practical embodiment of my invention l employ a gun frame lO'and barrels 11, the barrels having a depending lug lla which lits between the fork end of the frame and turns upon the joint pin 12', a. fore-end iron 13 being used in connection with the barrels and frame to complete the assemblage of these parts.

It is preferred to arrange the hammers 14: having the main springs 15 connected thereto, the sears 16 and the sear springs 17 bearing thereon, mounted upon the side plates 18, these side plates being removably secured to the opposite sides of the frame 10. The rear ends of the sears are formed with lateral extensions 16a which extend immediately over the triggers 19 and 2O as most hook 21 pivoted at 21a in the slotted portion of the barrel lug 11a, the hook 21 co-acting with the hooked end 22a of the cooking lever 22, said cooking lever being pivoted within the frame. As before stated the hook 21 is pivoted at 21, the pivot being adjacent the upper end of the hook and a spring 2li tends to throw the hook 21 down to the position shown in Figs. 7 and 8, so thatv the barrel can be disconnected from the stock when desired. This spring 24; is countern acted bye plunger rod 23 which is loosely mounted in the barrel lug and is caused to bear against the hook 21 by the abutting face of the fore-end iron 13 when the parts are assembled, as most clearly shown in Figs.

1 and 2, and when the iron 13 is in contact wigththe plunger rod 23 said plunder rod will hold the hook 21 in engagement with the hooked end 22a of the cooking lever` so that when the barrels are broken and thrown to the positions shown in Figs. 2 and 3 the cooking 'lever will be raised at its forward end and turned upon its pivot so as to throw the trunnions or lingers 22h rear wardly, these trunnions or lingers operating upon the hammers to force them back to a cocked position, Fig. 2 indicating the partially cocked position and Fig. 3 thev--completely cocked position.

it will thus be seen that I provid o. a simple and efhoient construction carried by the barrei which 'will ooact with the 'cooking lever for the purposeof-cocking the hammers and 'which mechanism can be rendered easily ineffective and readily detachable '-closed position l provide the barrels with a lump/or extension which is slotted at 25 to' receive alaterally swinging bolt 26 operated by the top lever 27 through the medium shown in Figs. '1, 2, 3,and 11.

of a pivot post 27a, and a spring 28 which surrounds a rod 28a pivotally connected to the rear end of the bolt 26 as most clearly The spring normally holds the boltV in its operative or 'closed position, the bolt entering the notch 25a when the barrels are closed as shown in Fig. 1 and when it is desired to breakthe barrels the top lever 27 -is shifted to one side compressing the spring 28 and rocking the bolt 2 6 so as to withdraw the same from the notch 25aand the barrels can then be thrown down to the position shown in Fig. 3 for the purpose of -recockingthe gun and also permitting the unloading and reloading ofthe For the purpose. of locking the bolt 26 vtemporarily in its open position, or in other vvwords the position shown in Figs. 2, 3 and 4f I employ a supplemental bolt or check 29 vwhich is mounted to slide vertically upward in the breech frame and is located just below lthe bolt 26 'as most clearly -shown in Figs. 4 and 5. -This supplemental bolt or check is illustrated in detail in Fig. 6, and v:from which it will be noted that it is rovided with webs or fins 29a and 29b w ich fit in corresponding slots in the breech frame 'and thereby prevent rotation of the check and guide the same in its movements. The web .29a is extended upwardly beyond the face of the bolt -29 as shown in Figs. 4 and 6, this extended iin or web being adapted to enter behind the edge of the bolt 26 or engage a notch in said bolt 26 as shown in Fig. 4 thereby locking said bolt 26 against any return movement, and aspring 30 held in place by a pin 30a Vnormally projects the supplemental bolt or check upwardly the moment the bolt 26 is thrown to one side by the -lever 27 and the lump or extension 25 withdrawn from the recess 10a produced in the frame. When-the end of the barrel is thrown into a closed position as shown in Fig. 1 the lower end of the lump or extension 25 engages ythe supplementalbolt or check 29 and forces the same down to the position shown in Fig. 5 and the spring 28 acting upon the bolt 26 immediately throws it into engagement with thenotch 25a so that the barrel is locked to the frame and the lever 27 will occupy its normal or central position.

` Having now described the manner of connecting the` barrel wand frame, and co-acting parts for cooking the hammers and also the means `for locking and unlocking the barrel I will now describe the safety 'device which mounted to slide .on the under side of the top of the frame 10, this spring bar 31 having a depending arm- 31a which is adaptedi to engage the lateral extensions 16 of the sears 16 as more fully explained hereinafter.

At its rear end the bar 31 carries a roller 32 which is adapted to engage either one of the two notches 33 and 34 out in the under side of the top of the frame asl most clearly shown in Figs. l, 2 and 3, the notch 34 being preferably of greaterlength than the notch 33. A xed post 10 is arrangedwithin the frame 10 and has a push rod 35 .slidably mounted therein, this push rod occupying a position between the cooking lever 22 and the depending safety arm 31a, the length of this push rod being such, that when the cooking lever is forcing the hammers to full cock the said rod will operate and force the arm 31'a rearwardly suflicien't to move the rear end of the arm 3l withits roller 32 from the notch 33 into the notch 34 as shown in Fig. 2, and-in the meantime the safety arm 31a is prevented from completing its rearward movement by the sea-r extensions 16*l which block its way as is also shown in Fig. 2, the forward ends of the sears being depressed and their rear ends elevated until the hammers reach` full cock and when they do-reach full cock the for-` ward. ends ofthe sears engage the hammer notches and theirrear ends then drop to the position shown in Fig. 3 and the safety arm 31a is allowed to complete its rearward movement. The safety arm 31a then lies immediately over the sears and the fire arm cannot possibly be discharged until .the

safety arm is moved forward, and this isaccomplished' through the thumb piece 36 mounted on the upper side of the frame 10 and connected to the sliding arm 31.

The movement of the safety arm 31a from a position shown in Fig. 2 is performed by the roller 32 co-acting with the `inclined wall" of the notch '34, so soon as the sear nose moves into the hammer notch 'afnd thus allowing the rear end of the scar to drop to a position below the end of the arm 31a..

It will thus be seen' that I provide a simple durable and eicient lire arm mechanism capable of accomplishing the objects hereinbefore referred to.

What I claim is 1. ln break down gun, the combination with a barrel and frame, of a spring actuated hook carried by said barrel, ajhammer and sear and safety arm carried by 4the frame, a push rod adapted to operate uponv said safety arm and a cooking lever adapted to be engaged by the barrel hook and operate upon *the hammer and push rod as set iorth.
